"WebThe Huber loss is both differen-tiable everywhere and robust to outliers. A disadvantage of the Huber loss is that the parameter α needs to be selected. In this work, we propose an intu-itive and probabilistic interpretation of the Huber loss and its parameter α, which we believe can ease the process of hyper-parameter selection. " - Huber loss 1964
